    Bluetooth: SCO: remove the redundant sco_conn_put
    
    When adding conn, it is necessary to increase and retain the conn reference
    count at the same time.
    
    Another problem was fixed along the way, conn_put is missing when hcon is NULL
    in the timeout routine.
    
    Fixes: e6720779ae61 ("Bluetooth: SCO: Use kref to track lifetime of sco_conn")
